MedicalResearch.com: What are the main findings of the study?
Answer: This study in 11-12 year old children shows that self-reported characteristics of sleep quality were not associated with blood pressure and HbA1c; and that in girls, but not in boys, some sleep characteristics were associated with anthropometric outcomes (BMI, waist circumference) and cholesterol levels. More specifically, in girls, longer time in bed was associated with lower BMI and waist circumference; having night-time awakenings with higher total cholesterol, going late to bed while rising early with higher total and HDL cholesterol; and feeling sleepy/tired during daytime with lower HDL cholesterol and with higher total-to-HDL cholesterol ratio. We report new findings for daytime outcomes of sleep quality that were not studied before in relation to cardiometabolic risk; e.g. difficulty with getting up in the morning, feeling rested after waking, and feeling sleepy or tired during the day. Our study therefore offers insight not only in characteristics of sleep at night, but also in consequences of sleep during the day.
